vehicle 1. On the forward end of the vehicle 1 are mounted bearings 4 inwhich is JOllIIlitlGd. a.vert1cal shaft 5 adapted to be rotated by ahand wheel 6. A drum 7 is secured to the shaft 5 and is located betweenthe bearings 4. Flexible elements 8 are wound in opposite directionsaround the drum 7, the flexible elements being carried over idlers 9 onthe forward portion of the vehicle 1, the ends of the flexible elementsI being secured at 10 to the horizontally movable frame 3.

When the shaft 5 is rotated by means of .the hand wheel 6, one of theflexible elements 8 is wound upon the drum 7 and the other of theflexible elements is paid on the drum. In this way, a horizontalswinging movement may be imparted to the frame 3,

the latter swinging on the pivot pin, 2. The

ob ect attained b this horizontal swinging- -of the frame 3 is thatfirst the auger 43,

hereinafter described, may be disposed properly to bore a hole in theground, the hammer 18 (he einafter described) subsequently bGiH'gdISPOSGd above the hole made bythe auger 43, so that the hammer may beused for driving a post or pile into the hole made by the auger.

Upright guides 11 are carried by the forward end of the frame 3, theguides being sustalned by rearwardly extended braces 12 The'iuldes 11are connected at their upper ends cross bars 14 carrying a bracket 15 onwhich a sheave 16 is journaled. A flexible element 17 is trained acrossthe sheave, one end of the flexible element being attached to the hammer18 hereinbefore a1- luded to,'this element being mounted to reciprocateon the guides 11. The rear end of the flexible element 17 is attached toa drum 19 carried by a shaft 20 journaled in bearings 21 mounted on theframe 3. The drum 19 and coacting parts may be of any desired form, thenumeral 22 denoting conventionally a brake whereby=the rotation of thedrum 19 is limited, thereby to hold the hammer 18 against movingdownwardly. A gear wheel23 forms a part of the drum 19 and meshes into aloose pinion 24 on a shaft 25 carried by the bearings 21. A pulley 26 isfixed to the shaft 25. The numeral 28 marks a foot lever constituting apart of a clutch mechanism for coupling the loose pinion 24 to the shaft25 or to the pulle 26, so that when the pulley 26 is rotate the pinion24 and consequently the gear wheel 23 and the drum 19 will be rotatedalso. This mechanism may be of any desired form and various mechanismsadapted for the purpose in view are known 1n the art. The pulley 26 isengaged by a belt 29 trained around a pulley 30 on a shaft 31constituting a part of an engine 32 mounted on the rear end of the frame3. a

' It will be obvious that when the shaft 31 is driven by the engine 32,the pulley 30 will.

operate the belt 29, the latter driving the pulley 26 and. the pulley 26rotating the pinion 24, the parts'26 and 24 being coupled up releasablyby theclutch mechanism of which the foot lever 28 constitutes a part.From the pinion 24 motion is transmitted to the drum 19 by way of thegear wheel 23 and the flexible element 17 may thus be reeled onto thedrum' 19, elevating the ham- Iner 18. The clutch mechanism of which thefoot lever 28 constitutes apart may be manipulated to release "thepinion 24 from the shaft 25, the drum 19 being held by the brake 22until it is desired to drop the hammer 18. Then, by a manipulation ofthe brake, the drum 19 may be released, and the hammer 18 will ridedownwardly on the guides 11 to drive the post or pile.

Standards 33 are erected on the frame 3 to one side of the guides 11 andat the rear thereof, one of the standards being suitably sustained by abrace 34. The standards 33 carry blocks 35; the blocks 35 of therespective standards 33 being connected to angle iron guides 36. Thenumeral 37 marks an upper cross bar, an intermediate cross bar is shownat 38, and the lower cross bar is shown at 39. The ends of the crossbars 37 38-and 39 are secured between the angle iron guides 36. Thecross bars 37, 38 and 39.

carry caps 40 retaining bearings 41, in which an auger shaft 42 ismounted to rotate and to move endwise. Attached to the lower end of theauger shaft 42 is auger 43. The auger shaft 42 is splined as shown at 44to a pulley 45 supported for rotation in horizontal plane by the lowercross bar 39, the construction being such that when the pul ley 45 isrotated, the auger shaft 42 will be rotated also, it being possible forthe auger shaft 42 to have a vertical movement in the pulley 45- A belt'46 is trained around the pulley 45 and is engaged around a pulley 47loose on the engine shaft 31, but adapted to be connected thereto by aclutch 48. When the clutch 48 is thrown in, the pulley 47 will becoupled to the shaft 31. Motion will be transmitted from the pulley 47by way of the belt 46, through the pulley 45 and thence into auger shaft42 and the auger 43.

Numeral 49 denotes a cross head in the form of a bar, the ends of whichare, mounted to slide vertically between the guides 36. The cross head49 carries a bushing 50 in aeracee which is journaledfor rotation, aspool 51' which is flanged to engage the upper and lower edges of thecross head, the spool 51 being keyed as shown at 52 to the auger shaft42. The auger shaft 42 and the spool 51 rotate with respect to the crosshead 49,

but when the cross head is raised and lowered, the auger shaft 42 willbe raised and.

53 is trained around a sprocket wheel 56 secured to a shaft 57 ournaledon the stand ards 33. A sprocket wheel 59 is loose .on

the shaft 57, but may be connected thereto by means of a clutch 58. Thesprocket wheel 59 is engaged by chain 60 passed around a sprocket wheel61 secured'to the shaft 31 of the engine 32.

The engine shaft 31 drives the sprocket chain 60 by means of thesprocket wheel 61. The sprocket wheel 59 may be coupled to the shaft 57and be disconnected therefrom by means of the clutch 58. From the shaft'57 motion is transmitted by way of the sprocket wheel 56 and thesprocket chain 53 through a cross head 49, the cross head thus beingraised or lowered, by power.

A shaft 62 is supported for rotation on the standards 33 and is adaptedto be rotated by a hand wheel 63. A drum 64 is secured to the shaft 62.A flexible element 65 is wound around the drum 64. One end 66 of theflexible element is trained upwardly and then downwardly over an idler67 carried by the upper cross bar 37 and is attached to the cross head49. Theother end 68 of the flexible element 65 extends upwardly from thedrum 64 and is attached to the cross head 49. The shaft 62 may berotated by means of the hand wheel .63, the end 66 of the flexibleelement serving to raise the cross head 49 and the auger shaft 42 andthe end i 'tion with the various component mechaglvenatthis nisms, but aresume will be point.

In order 'to position the auger 43 properly, .the frame3 may be swung onthe pivot pin 2 by means of the hand wheel 6, the shaft 5 and theflexible elements 8. The clutch 28 is manipulated so as to disconnectpinion 24 from pulley26, thereby preventing the drum 19 from beingrotated when it is desired to feed "58 1s manipulated to essence theengine 32 is put into operation. The brake 22prevents thedrum 19 fromrotating under the weight of the hammer 18, and the hammer 18 remainselevated as shown in Fig. 3. I

The clutch 58 is operated to disconnect the sprocket wheel 56 from theshaft 57. The clutch 458 is operated to connect the pulley 47 to theengine shaft 31. The engine shaft'31 thus is made efiective to rotatethe auger shaft 42 and the auger 43, through a driving train com risingthe pulley 47, the belt 46 and thep ey 45. If the auger shaft 42 thenthe clutch 58 downwardly, by power, is thrown in to operation, downwarddrive is imparted to the auger shaft 42 from the engine shaft 31 bymeansof the sprocket whee 61, sprocket 0 sin 60, sprocket wheel 56, and thesprocket chain 53. If the direction along travel of the chain 66 isreversed, the auger shaft 42 and the auger 43 maybe elevated. The augershaft may be raised or lowered by hand through the instrumentality ofthe wheel 63, the shaft 62, the drum 64, the flexible element 65.

After a hole has beenbored by means of the auger 43, the auger shaft 421s raised as hereinbefore outlined. The frame 3 may be swung on thepivot pin 2 by means of the hand when 6; the elements 8, until thehammer v18 is alined vertically wi h the hole which has beenboredb theauger 43. The clutch 48 is operate disconnect the pulley 47 from theengine shaft 31, and. consequently the auger shaft 42 is not rotated.The clutch disconnect the sprocket wheel 56 from the shaft 57, and novertical movement is imparted to the auger shaft 42. Through the mediumof the clutch operating means 28, controlling the connection betweenthepinion 24 and the pulley 26, the drum is maybe operated from theenginse 32 to control the reciprocating haer the hole bored by the auger43 thus bein brought about.
